Abstract

This study was conducted to suggest the cause analysis and mitigation measures of foaming generated in the effluent of wastewater treatment plant. The foam generated in the outlet connected with the tidal river system was identified as structural problems. And the main cause of foaming was air entrainment by an impinging jet and the internal accumulation by the diffusion barrier. In consideration of these conditions, it present the effective ways such as micro-screen and submerged outlet, to mitigate the foaming generated in the water channel and outlet end.

본 연구는 하수처리장에서 최종 방류되는 하수처리수의 거품발생 원인분석과 저감방안을 제시하고자 수행되었다. 감조하천의 방류구에서 거품이 발생하는 것은 구조적인 문제점으로 파악되었다. 거품은 낙차에 의한 공기 연행과 확산방지막에 의한 내부축적이 주요한 원인이었다. 이러한 여건을 고려하여, 방류수로와 방류구 종단에서 미세스크린과 수중방류를 통해 거품발생을 완화시킬 수 있는 효과적인 방안을 제시하였다.
